T 0 all whom it may concern:

Be it known that I, CHAnLns B. WVANA- MAKER, a citizen of the UnitedStates, residing at Indianapolis, in the :county of Marion and State ofIndiana, have invented a new and useful Collapsible Stand, of which thefollowing is a specification.

It is the object of my invention to provide a collapsible and adjustablestand, particularly adapted for use as a support for orchestra bells,Xylophones, and other orchestral instruments.

The accompanying drawings illustrate my invention. V

Figure 1 is a perspective view showing the stand open, and supporting aset of orchestra bells shown in outline; Fig. 2 is a perspective viewshowing the stand collapsed; Fig. 3 is a cross section showing the clamping device for the two sections of the upright; Fig. 4 is a detail ofthe locking device for the upper arms; and Fig. 5 is a detail of theattachment of one of'the toggle links to the lowerend of the upright.

The upright comprises two telescoping members 10 and 11, the upper endof the outer member 10 being split at 12, as shown in Fig. 3, andprovided with, a clamp 13 for clamping the two members 10 and 11together in any relative movement between them. The clamp 13. forms partof a fitting 14. fixed to the upper end of the section 10. and providedwith a plurality of bifurcated projections 15 between the bifurcationsof which are pivoted the legs 16. The legs 16, shown as four in number,are somewhat longer than the section 10, and the lowerend of each leg isconnectedto a fitting 17 at the base of such section by means. of a togle 1': comprising two links 18 and 19. The links 18 are substantiallyas much longer than the links 19 as the legs-16 are longer than thesection 10, so that when a toggle is collapsed the corresponding leg 16is bent down substantially parallel to the section 10; and the.

sum of two cooperating links 18 and 19 is such that when such links areextended they form one-side of a rightangle triangle of which thesection 10 forms the other side and the leg 16 the hypotenuse. Each link19 is provided with a pin 20 which cooperates with a shoulder 21 on thefitting 17 to prevent the toggle from being broken downward.

Application filed October 14, 1912. Serial No. 725,701.

On the upper end of the section 11 is fixed a fitting 28, on which arepivotally mounted a plurality of arms 26, shown as four in number. -Alink 27 ispivotally attached to each arm 26 and to arfitting 28 slidablymounted on the section 10 between the two fittings 14: and 17. Bysliding the fitting 28 alongthe section 10 relatively to the fitting 25,the arms 26 may be swung either substantially parallel to the upright orinto a plane at right angles thereto. latter position, they form asupport, on which may be placed anything desired; par- I orchestra bellsor other orchestral instrument. In order to keep the arms 26 fromswinging downward, a locking bar 29 is pivoted at one end to :thefitting 25, conveniently on the pivot on which one of the arms 26 ismounted, and is provided at the other end with a notch 30 whichcooperates with a pin, conveniently the pivotpin for one of the links 27on the fitting 28. 'The notch 30 is, substantially L} shaped, so thatafter it is placed over the pin in the fitting 28 such fitting may bepushed downward slightly, thus locking the of this locking bar, thesection 11 may be adjusted in the section 10 without disturbing the arms26 of the instrument supported thereon.

I claim as my invention:

1. In a foldingv stand, the combination of two longitudinallytelescoping ,members, a

' longitudinally thereon, a plurality of links connecting said collarwith said arms, and a-rigid member releasably connecting said collar andthe inner of said members in definite longitudinal relationship wherebywhen the collar is slid along the outer member the inner member slideswith it.

2. In a folding stand, the combination of two longitudinally telescopingmembers, a plurality of arms pivotally connected to the inner of saidmembers, a collar mounted on the outer of said members, a plurality oflinks connecting said collar withsaid arms, and a rigid memberreleasably connecting said collar and the inner of said members indefinite longitudinal relationship.

3. In a folding stand, a tubular member, an inner member telescopingwith Said tubu- When in the 7 bar against swinging outward. By reasonmounted on said tubular the points where the first and second pluralilarmember, a folding base attached to said tubular member at twolongitudinally spaced points thereon, a collar on said tubular mem berand located betweensaid two longitudinally spaced points, and a foldingtop can ried partly by said collar and partly on said inner member, saidcollar being longitudinally movable on said'tubular member.

l. In a folding stand, a tubular member, a plurality of arms pivotallymounted on said tubular member at a fixed point longitudinally thereof,a second plurality of arms pivotally mounted on said tubular member at adifferent fixed point longitudinally thereof and shorter than the firstplurality of arms, a plurality of links connecting the arms of saidfirst plurality of arms with the arms ofthe second plurality of arms, aninner member telescopingly mounted in said tubular member, a pluralityof arms hinged on said inner member, a collar slidably member betweenties of arms are mounted, and links connecting said collar with the armspivotally mounted. on said inner member.

5. In a folding stand, a tubular member, a plurality of arms pivotallymounted on saidtubular member at a fixed point longitudinally thereof, asecond plurality of arms pivotally mounted on said tubular member at adifferentfixed point longitudinally thereof and shorter than the firstplurality of arms, a pluralityof links connecting the arms of said firstplurality of arms witli the arms of the second plurality of arms, aninner member telescopingly mounted in said tubular member, a pluralitvof arms hinged on said inner member, a collar slidably mounted on saidtubular member between the points where the first and second pluralitiesof arms are mounted, linksconnecting said col.- lar with the armspivotally mounted on said inner member, and a rigid connecting memberfor connecting said collar and said inner member so that they may bemade to sllde together relatlvely to said tubular member.
